|---|---|---|
Confirmed ORR | Defined as the percentage of study participants in whom a confirmed CR or confirmed PR (assessed per RANO 2.0) is observed as best overall response.

Duration of response | For Treatment Arms 1 and 2 only. Defined as the time from first objective response (CR or PR as assessed by BICR and investigator per RANO 2.0) to first occurrence of objective tumor progression (progressive disease as assessed by BICR and investigator per RANO 2.0), or death from any cause, whichever occurs first. | Up to 24 months |
Disease control rate | For Treatment Arms 1 and 2 only. Defined as the percentage of study participants in whom a confirmed CR or confirmed PR or stable disease (assessed by BICR and investigator per RANO 2.0) is observed as best overall response. | Up to 24 months |

Pharmacokinetic (PK) assessment: Maximum concentration (Cmax) of pumitamig | For Treatment Arms 1 and 3 only. As data permits. | From the first dose of study treatment until 90 days after the last dose of study treatment (up to 27 months) |
PK assessment: Minimum concentration (Cmin) of pumitamig | For Treatment Arms 1 and 3 only. As data permits. | From the first dose of study treatment until 90 days after the last dose of study treatment (up to 27 months) |
The prevalence and incidence of anti-pumitamig antibodies | For Treatment Arms 1 and 3 only. From before the first dose of study treatment until the last survival follow-up visit.
ADA prevalence is the proportion of study participants with positive ADA against pumitamig at any point in time (baseline or post-baseline) during the study period.
ADA incidence is the proportion of study participants with treatment-emergent ADA against pumitamig during the study period. Participants with treatment-emergent ADA includes study participants who were ADA negative or missing at baseline and became ADA positive post-baseline (treatment-induced ADA), and study participants who were ADA positive at baseline and post-baseline but had an increase in ADA titer of defined threshold from baseline to post-baseline (treatment-boosted ADA). | Up to 27 months |
